Tinned copper flat steel manufacturers spot wholesale

 Tinned copper flat steel using well-known vendor of A3, Q235,45 # steel plating introduce world-class technology, the perfect combination of copper and steel. Ningbo Enron produced tinned copper flat, just how do you bend the copper layer will not peel, crack. A length of 6 m, copper layer thickness from 0.05-0.254mm, available to customers. Tinned copper flat package wrapped bags commonly used approach, 10 a bundle, with wire two pitched. Also available tray packaging, forklifts also convenient. Lightning Protection project uses large, flat tinned copper grounding conductor is an excellent level. Because the material is straight, using exothermic welding method is very convenient. Generally vertical grounding conductor copper grounding rods make reliable connections, and network through, grounding resistance is easy to down, depending on the superior conductivity of copper material. Tinned copper flat is also a leader in terms of corrosion resistance, grounding should the use of copper layer thickness 0.254mm material, maintenance-free life expectancy will reach 50 years. Also a customer noticed that when tin-plated copper flat steel factory colors are bright, shiny, transportation is very capacity trek damaged packaging, material color becomes dull, but please be assured that only the copper oxide layer only, does not affect the use of effects and life . Tinned copper flat compared with traditional galvanized steel, has a great advantage in ground engineering. First of all, greatly reduced quantities. To achieve the design of ground resistance, excellent electrical conductivity copper material can save a lot of material; secondly, life greatly improved. Copper and iron corrosion rate, we knew pretty well; again, exothermic welding copper materials commonly used to make the connection, the joint achieve molecular level binding, it does not disconnect, and galvanized steel using a welding joint easy to fall off , there breakpoints, to the entire above ground portion of the device poses a great security risk. Copper flat steel prices, copper flat steel manufacturers preferred speed of Ningbo, copper coated steel - Copper Flat Copper Flat -BSDX3-IS160 The company provides world-class plating by plating technology on low-carbon steel over 99 percent purity electrolytic copper from, copper layer thickness of 0.254mm or more points, the specific application: for equipment grounding deflectors, and network level ground conductors, cable channel and tower level ground conductor wiring neat and convenient. Copper flat level ground with other conductors compared with huge advantages: cheaper prices. Although the unit price of copper than the flat galvanized steel unit price is high, but it galvanized steel strong current conduction ability and age than others. Because the amount of copper flat current conductivity higher than that of galvanized steel, with a grounding in the project to achieve the same power and ground resistance drainage, copper flat less than galvanized steel. Comprehensive comparison with a grounding in project cost and copper flat steel grounding system cost considerably. Again from a long-term comparison, the use of flat copper grounding system life for 40 years, and the use of galvanized steel grounding system maximum useful life of only 15 years. Galvanized steel grounding system every few years to maintain the excavation and reconstruction. Grounding system transformation more costly and time-consuming than a new ground. Over time the cost of copper than the galvanized steel flat single cost is lower. Excellent corrosion resistance, service life of up to 40 years. Installation of galvanized steel corrosion resistance of copper is ten times more than steel, copper is three times more than galvanized. The corrosion resistance of copper steel is close to copper, the copper surface will produce strong adhesion oxides (P. Cu (OH) 2), on the inside of the material has a good protective effect, blocking the further corrosion formed copper steel widely used in European countries grounding system certification standards for the quality of this earth materials are UL467, the standard page 11 clearly defined in Chapter 9 of the thickness of the copper grounding rods material must be greater than 0.25mm, Copper and copper flat strands of copper material of greater than 0.070mm ground network to network 40 years to ensure maintenance-free. Current conducting ability. 20? C temperature, the resistivity of copper is 17.24 × 10-6 (Ωomm), the resistance of the steel was 138 × 10-6 (Ωomm). Assuming that the electrical conductivity of copper reference value of 1 (or 100 percent), the angles and galvanized steel bar conductivity rate was 8.6 percent, electrical conductivity copper steel more than 20%, while copper coated Strand conductivity was 30 percent. In the lightning current high-frequency current is applied, copper steel materials can produce skin effect, conductivity close to pure copper, is much higher than steel grounding. Also copper relative to the vacuum permeability is 1, the steel is 636 times, the lightning current or fault current through the impedance of a copper conductor grounding is far less than steel, and therefore caused by the impedance ground potential rise sideswipe probability will be generated greatly reduced. Copper flat as equipment grounding deflectors, and network level ground conductors, cable channel and tower level ground conductor generally copper, copper flat steel, galvanized steel three. Drainage effect and corrosion resistance of copper is the best ,, most suitable equipment grounding deflectors, and network level ground conductors, cable channel and tower level ground conductor. But the high price of copper, and will be little sneak. Galvanized steel is level ground conductor now the most widely used, but its effect of drainage and corrosion resistance is not how good. Copper plated steel is a new bi-metallic composite materials, it has both high strength steel, excellent flexibility, greater thermal resistance and high permeability, there are good copper conductivity and excellent corrosion resistance, the market Copper on steel products, generally there are three processes, one is electroplated, one is a copper-clad, there is a level of continuous casting, horizontal continuous casting cost is very high, generally for grounding copper steel products do not use this process. Plating: The high purity copper by electrolysis principle, it is completely attached to the steel core, forming an alloy of molecular-level structural steel in copper bonding surface, fully integrated dual-metal interface, enabling ductile metallurgical connection between the copper and steel and integrally formed flat copper, copper clad steel
